Feldman said Haim revealed his own suffering when the two grew close shooting the 1986 flick Lucas, saying, "…an adult male convinced him that it was perfectly normal for older men and younger boys in the business to have sexual relations, that it was what all the guys do. So they walked off to a secluded area between two trailers… and Haim allowed himself to be sodomized."

Feldman also says that while some huge Hollywood names like directors Steven Spielberg and Richard Donner became trusted friends, others adults did him great harm.

One he calls "Ron," who was an assistant to Feldman's father who in turn was acting as the young actor's manager, used his position to take advantage of the teen. Feldman describes how "Ron" took Feldman out partying, gave him a concoction of booze and drugs and had oral sex with the "petrified" and "revolted" teen.

In another passage, Feldman discusses a photo from his 15th birthday party where he and Haim are flanked by five men — all of whom he claims were sexually abusing them.

"Slowly, over a period of many years, I would begin to realize that many of the people I had surrounded myself with were monsters," he says.

The one person with whom Feldman felt he could truly escape the horrors of his life was, surprisingly, Michael Jackson — who he insists never even attempted to molest him.

"I was shattered, disgusted, devastated. I needed some normalcy in my life. So, I called Michael Jackson," he writes. "Michael Jackson's world, crazy as it sounds, had become my happy place. Being with Michael brought me back to my innocence. When I was with Michael, it was like being 10 years old again."

The pair's friendship ended in 2001 when Jackson mistakenly believed Feldman was going to trash him in a book.

Both Feldman and Haim's drug use spiraled out of control, with Feldman claiming at one point he was "having regular coke-off challenges" with comedian Sam Kinison, "daring each other to see who can stay up the longest, who can do the most rails."

Haim's drug problems grew even worse, and he was in and out of rehab multiple times before dying of pneumonia in 2010.

"People always ask me about life after childhood stardom," Feldman writes. "What would I say to parents of children in the industry? My only advice, honestly, is to get these kids out of Hollywood and let them lead normal lives."
